Missouri consistently ranks among the states with the lowest average gas prices, and Costco's 9 warehouse locations — spanning St. Louis, Kansas City, and Springfield — typically undercut even the local average by 10 to 30 cents per gallon. For daily commuters along I-70 or I-44, the savings from filling up at Costco can be substantial over the course of a year. Missouri's relatively low state fuel tax already keeps pump prices competitive, and Costco membership pricing layers additional savings on top.
Because fuel prices fluctuate daily with crude oil markets and regional supply changes, we do not publish specific per-gallon prices on this page.
